Whether you need a hydraulic pump for a forklift, excavator, large industrial press or any other machine that uses hydraulics, there are many factors to consider when selecting the right pump. Parker makes thousands of hydraulic pump models for every application and industry. Here are some tips to help you choose the ideal pump for your needs.
Consult The Parker Hydraulic Pump Catalog
Parker has an extensive catalog with over 20,000 hydraulic components including hydraulic pumps. Start by browsing the Katalog Pam Hidraulik Parker to get an overview of what options are available for your application. The catalog contains technical specifications and schematics to help you determine the base mount style, size, kadar aliran, pressure requirements and more for your pump.
Determine The Flow Rate You Need
The flow rate, measured in gallons per minute (gpm), determines how fast fluid will flow through your hydraulic system. To find the required flow rate, consider the size of the hydraulic cylinder(s) used in the machine as well as the speed needed to actuate the hydraulic functions. Most industrial pumps have adjustable flow rates so selecting a pump that provides 10-20% more flow than required will give you more flexibility.
Select The Right Pressure Rating
The pressure rating determines the maximum allowable operating pressure of the hydraulic pump. Match the pump’s pressure rating to the pressure requirements of the hydraulic actuators, valves and cylinders in your system. Having a pump with a higher pressure rating compared to the system pressure allows for some overhead but too wide of a margin can be inefficient.
Consider Base Mount Options
Parker offers a variety of base mount styles for hydraulic pumps to interface with different types of machines. Common base mount options include SAE flange mounts for industrial applications and cartridge mounts for compact equipment. Other styles include face mount, foot mount and taper mount.
Purchase Replacement Hydraulic Pump Parts
If replacing an existing hydraulic pump, measure key dimensions to ensure a compatible replacement. Also make note of Parker part numbers for any O-rings, seals, bearings and valves used in the old pump. These bahagian pam hidraulik can often be reused in the new pump, saving time and money during installation and commissioning.
Include Hydraulic Motors In Your Search
Parker offers a wide selection of hydraulic motors to perfectly match the hydraulic pumps you select. Parker hydraulic motors are available in piston, vane and gear configurations to efficiently convert hydraulic flow and pressure into rotational torque. Consult the Parker hydraulic motor catalog to find hydraulic motors to complement your pumps.
Choose A Pump With Appropriate Materials
Select hydraulic pumps constructed from materials that can withstand the operating environment, fluid type and potential contaminants in your application. Common material options for Parker hydraulic pumps include cast iron, hardened steel and aluminum with a range of shaft, bearing and seal materials also available.
